This kind of brain cramp calls for tough love.
If I was Popp, I'd let Duron know that he's being paid a whopping big salary to play, not to take himself out of the game cuz he's too ruffled to help his team.
I'd let Duron know that some of his team mates took pay cuts to compensate for his whopping salary.
I'd let him know that if he keeps this up, he can kiss the NFL goodbye for good.
And I'd bench him for least one more game, to let the message sink in. And next time he opens his big yapper and draws a flag, he's out for at least one series.
